python - 销毁 tkinter 按钮

Question

我在 Tkinter Python 中创建了一个应用程序，该应用程序在存档中搜索多个许可证，然后将结果分组到世界列表中。找到许可证后，会出现一个按钮，如果我按下该按钮，则会在滚动文本中显示结果。我的想法是，我无法删除搜索后出现的(重新启动)按钮。有人可以帮我解决这个情况吗？ 我怎样才能销毁mit_bt？

def print_to_textbox_Mit(wordlist):
    if len(wordlist) >= 1:
        mit_button()

def mit_button():
    mit_bt = tk.Button(window, text= " M I T ", relief="groove", command=mit_print_text, activebackground="#800020").place(x=10, y=10)

def mit_print_text():
    text_box.delete("1.0", tk.END)
    text_box.insert("0.0", "\n            !!!!!! MIT !!!!!!")
    for lines in wordlist:
        text_box.insert("end", "\n"+lines)

def print_to_textbox_Mit(wordlist):
    if len(wordlist) >= 1:
        mit_button()

def mit_button():
    mit_bt = tk.Button(
        window,
        text= " M I T ",
        relief="groove",
        activebackground="#800020",
    )
    # configure your button's 'command' after declaring it above
    mit_bt.configure(command=lambda b = mit_bt: mit_print_text(b))
    # using a lambda here allows us to pass an argument to the 'command' callback!
    mit_bt.place(x=10, y=10)

def mit_print_text(button):  # pass your button as an argument to this function
    text_box.delete("1.0", tk.END)
    text_box.insert("0.0", "\n            !!!!!! MIT !!!!!!")
    for lines in wordlist:
        text_box.insert("end", "\n"+lines)
    # once you no longer need the button, call 'place_forget' on it to remove it
    button.place_forget()
